Cloud Nine is a relative newbie in the world of keyboards, as they've only been around since 2019. Its portfolio is also very small: Just two variants of the same C959 Ergo model, one ten keyless (the one being reviewed) and the other full-size.
It's an ergonomic keyboard and one with the main aspects required to help alleviate shoulder tension and wrist problems: Separated halves, tenting, and tilting. In the case of the first one, just picture a traditional keyboard chopped right down the middle and then fully separated.
